This is a used custom built 4i thru GW set of Titleist AP2's. They were used 1-1/2 seasons. Professionally built for a low handicap player. I have included a spec sheet on the build of these clubs. They were progressive shaft weighted before the build meaning the builder went through over 50 shafts of the same manufactured lot, to get the 8 shafts that met the weight progression. The shafts were then pured and laser flow aligned. Some people say you don't have to do that to steel shafts, well i say let them believe that cause i have seen as much as 3 cycles out on steel shafts no matter what brand. They were built +3/4" long for a 6'-2" player thus the slightly heavier swingweight. They were built with a swingweight progression throughout the set. This is similar to MOI matching. Gives you a better feel of the club by making them feel similar in weight. As a club gets shorter it has to get heavier to feel the same when you swing. You can't buy these clubs off the shelf. This is a very good set of irons for somebody looking to upgrade to a better quality and professionally built set. You will feel the difference. They are used so i would rate their condition 6 out of 10 because of that. Thanks for looking.
